She says it's because kids don't interact with analogue clocks much anymore and Covid lockdowns meant that a lot of kids never learnt it in school either. So apparently there is now a generation of kids who are around 10 - 12 who have no idea how to read the time from an analogue clock.
On the other hand, they are unintuitive, less common with every passing year, and I'd rather my children get any recess than add "learn to use another antiquated tool" into the school curriculum. I do complicated math for a living, but nobody's offended that I didn't ever get good at using a slide rule.
I can't remember the last time I saw someone with a mechanical watch other than as a fashion statement.
25 years ago, my household had mechanical alarm clocks, a mechanical clock on the oven, and multiple mechanical clocks on the walls of different rooms. Today, I think I might have a broken mechanical watch in my "you should probably fix these things" piles.
Having taught math to children, analog clocks are a great way to learn and apply fractions. I suspect that children's inability to read analog clocks tracks pretty well with their abysmal math skills, like fractions.
So maybe we don't "add" analog clocks to the school curriculum, but we instead replace some nonsense with analog clocks and fractions.
Kids were bad at fractions even before digital clocks.
Where we are, analog time-telling is a required part of the (common core) curriculum. So kids would have to learn it in school, though not necessarily internalize it for long enough that it would stick in the long run.
